What is meant by Raney?
: a finely divided nickel in the form of a pyrophoric powder or crystals or a suspension (as in alcohol) that is prepared from an alloy of equal parts of nickel and aluminum by dissolving the aluminum in warm sodium hydroxide solution and rinsing thoroughly and that is used as a catalyst for the hydrogenation of …
What does H2 and Raney nickel do?
It is typically used in the reduction of compounds with multiple bonds, such as alkynes, alkenes, nitriles, dienes, aromatics and carbonyl-containing compounds. When reducing a carbon-carbon double bond, Raney nickel will add hydrogen in a syn fashion.
What is Raney nickel and where it is used?
Raney nickel is used in a large number of industrial processes and in organic synthesis because of its stability and high catalytic activity at room temperature. It is typically used in the reduction of compounds that have multiple bonds, such as alkynes, alkenes, nitriles, dienes, aromatics and carbonyls.
What is the formula of Raney nickel?

Raney nickel/Formula
What is a nickel catalyst used for?
Nickel-based catalysts are widely used in petrochemistry for selective hydrogenation of poly-unsaturated compounds formed during steam cracking, such as dienes and/or alkynes.
What is Raney nickel Class 12?
Raney nickel, also known as spongy nickel, is a solid substance which is made up of nickel that is obtained from an alloy of nickel and aluminium. The primary application of this solid is its use as a reagent & catalyst for many hydrogenation reactions in the field of organic chemistry.
How much does Raney nickel cost?
Raney Nickel Catalyst, Grade Standard: Chemical, Rs 1000 /kilogram | ID: 18916390548.
Why is nickel the best catalyst?
Nickel and Noble metals so special as preferred hydrogenation catalyst because , these metal leaves large surface area for adsorption. Small amount of catalyst is required with easy workup & handling. The catalyst remains active for longer period of time and can be used repeatedly.
